It is established that the high concentrations Zr, REE and Y are developed in residual syenitic melt, which are the products of differentiation of basitic mantle melt . The separation and accumulation of ore minerals with formation of industrial concentration it is possible only in the conditions of the low viscosity of melt. A fluorine is the effective activator of of melt convection and ore minerals cumulation. Composition of alkaline feldspar and femic minerals are the effective indicators of degree of differentiation of syenitic intrusions. Product Description popup.authors popup.nrat_date 2020-04-02 Close
